Just because something is complex, doesn't make it wrong!
It's not complex, it is not behaving as most people think it is, or are familiar with AND there is not 'help' for these buttons (in contrast with the functions, where you could describe this behaviour). As said, it was my frustration (as in: instead of just 'using' I ended up trying and testing) that I "lost" labels just because whole records were ignorred, because certain columns had NULL values, and I ended up with an overly complex expression which tested IF the value was NULL. It's when I thought it was a bug that I found that other people, also had been there, AND found that there was another 'concat' function behaving a little different. In general I prefer a single intuitive working way of doing things, do I agree that 'intuitive' is very personal :-( Regards, Richard Duivenvoorde _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
